I am new to this site and this is my first post/thread, but I need help I have a 96 Powerstroke 4x4 auto. I've owned the truck about 3 months now and need some info. My truck EVERY TIME you crank it cold or not it lopes like its got a serious cam and will not smooth out until you press the fuel peddle. Most of the time I get in press the peddle a 1/8 of the way down and it cranks like normal. But if I don't it will lope every time until you press the peddle and hold it for like 3 or 4 sec. Any ideas . I've done had to replace the cam sensor, fuel pump, cleaned fuel lines, oil sensor, temp sensor, and fuel filter twice by Ford place. The lady at the Ford place where I live said it was my injectors and I had 2 putting out low. But me and my mechanic who's a 60 year old retired diesel mechanic says that if it was injectors it wouldn't smooth out by just giving it a little fuel. He said something about a fuel pressure regulator sensor, but I don't want to start replacing things that is not needed. Any ideas .

The #8 injector fires right after #6, which depletes the high pressure oil rail. Read up on the HEUI system and you'll understand.
More than likely, it's a HPO issue. Maybe fuel, but probably not. Either the HPOP is very weak, or something else, like ICP or IPR. If could be the UVCH, the wires going to the injectors, but if it's smooth other than the starts it's probably not.
Mine does this under pretty cold conditions, but not all the time. Yours just sounds really weak.

Ford dealership will RAPPPEEEEEE you. If you get any parts go to the International dealer or your local parts store. I bet you the lady at the front desk doesn't deal with these trucks often if at all.

As for your loping at start up it is pretty common with these trucks at this age. Mine does the same thing and it's my DD. I know it needs work but you have nothing to worry about. Do the basics such as UVCH, glow plugs, gpr, valve cover gaskets, check your fuel pressure, replace fuel bowl o-rings, change oil, and check all of your wiring. This is a small start and with the proper diagnostics you wont be blowing money at the dealership.
